On Sunday, German federal prosecutors took over the investigation following Friday’s knife attack in Solingen, Germany, that killed three and injured eight others, with at least four suffering serious injury. After a day-long manhunt, the assailant, Syrian-born Issa Al H., turned himself into the police. Investigators suspect terrorism as the motive, claiming that Issa Al H. is a member of a terrorist organization abroad. The attacks took place during the town of Solingen’s festival celebrating its 650th anniversary.
